Retro-gaming on Mactel/OS 10.4 (was Re: Semi-OT: Classic Mac support gone from Leopard (OS X 10.5))

Of course your apps might not be "carbonized" (I think > those are the right terms, it's been years, and it's late). Hmm... I haven't tried screwing with it too much... I tried doing a 'fink' or one of the other distro tools - it fetched the Dosbox source just fine, but the compile stopped when it failed to locate X11.h or something similar. I have it on the system, so it's probably a Makefile assumption as to INCLUDEPATH or something similar. I just haven't had time to dig into it. It's really just to play DOS games ("Master of Orion I", "X-COM", "Colonization", etc.) so I'll probably dig into it in the depths of Winter at Pole, when I'm bored and need a nostalgia fix. It's entirely uncritical for "real" work. > I suspect you are out of luck. Most of us with non-Mac OS X apps are > trying to run stuff so old that they're 68k apps.

As I thought... but I don't think they have released a Mac OS X version of "Starcraft" and "Starcraft: Broodwars" - more unessential retro-gaming. I do have genuine copies of both for Windows, so it's probably easiest to just finish setting up Parallels and run the DOS versions. I was just hoping to stay native where native was possible, but not, apparently, in this case.

CompacTape

by silent700＠gmail.com

I just received my shipment of items from this auction: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=220149564798 which should have been a load of recyclable TK50 media. Instead of CompacTape, however, they are all CompacTape III. I think these were TK85 2.6gb media. Does anyone know if they will still be writable with the standard format in a TK50? Or do I have a bunch of useless DLT I tapes?

EPROM Death?

I have found some vendors eproms need a little more time to cook. Ove 26 years I think I've only seen one that really had a stuck bit and that was a blown output pin. Allison

Experience with Dysan drive tester?

by trixter＠oldskool.org

A friend might have a Dysan Pat-2+ 5.25" floppy drive tester held for me, but we both have no experience with it. Assuming it comes with the alignment disk and manual, and functions, is it a worthwhile piece of equipment to have? I am not a die-hard techie -- I do not own an oscilloscope -- so I might grab it to keep my drives aligned, but not if it's more placebo than functional. If anyone has had experience using this unit or one like it, I'd like to hear your thoughts. -- Jim Leonard (trixter at oldskool.org) http://www.oldskool.org/ Help our electronic games project: http://www.mobygames.com/ Or check out some trippy MindCandy at http://www.mindcandydvd.com/ A child borne of the home computer wars: http://trixter.wordpress.com/

Finally! We have video of Chuck Peddle @ VCF East 4.0

by evan＠snarc.net

Thanks to Dave Haynie and Robert Bernardo. Chuck's talk begins around 15:00 into part 1. Part 4 ends just as he was concluding - and then the Skype PC when blue-screen on us. No video yet of the post-Chuck celebration, which is when the audience got to ask questions of Dave, Bil Herd, and Bob Russell, and when we sang "Happy Birthday to the Pet" with a chocolate chickenhead cake! 1. http://www.youtube.com/watch?v=PBnmJhEOdC8 2. http://www.youtube.com/watch?v=e1LeMNKHUbs 3. http://www.youtube.com/watch?v=dm8M5rdrDpA 4. http://www.youtube.com/watch?v=-_C1j8uSO_I Rumor has it that a DVD may soon be available. - Evan

Decmate I

by gkaufman＠the-planet.org

I have a reasonable Decmate I / PDP8 with dual RX02's in a tower and spare parts CRT/Keyboard, spare motherboard. It boots up nicely, includes serial port board and back cover. I've enjoyed it for the past year, but now have to get it out of my workspace. Open to a reasonable offer, especially if the buyer can pick it up in Southern NH. - Gary

Software Find at Thrift

by jrkeys＠concentric.net

While checking out a old hangout I found a copy of IBM's Hollywood software Version 1.0 (on 3.5 FD), complete in the box for $1.81 plus tax. There was not much else there like it was in the long ago past. Speaking of Hollywood, the Hollywood video store near us is closing and I went dumpster driving the other night and found that they had tossed all the video game cases that had been on display. Most but not all were empty, I found PS2 and PS3 DVD's in some of the cases. It got too dark and I had to stop pulling cases from the dumpster but there was over 150 cases left in the trash. John

SGI Crimson Questions & hardware request...

by derschjo＠msu.edu

Hi all -- Just picked up an SGI Crimson this afternoon, which should prove to be a fun machine to play around with once I get it running... a few questions for those who've dealt with these before... - What kind of power cable does this thing take? I've not yet seen anything like the connector on the back of this thing... can I plug this thing into a regular household outlet (that can supply the massive power requirements) or am I going to have to rewire my house? :) - What version of IRIX do you recommend running? I have a copy of 5.3, and 6.5, but I know that 6.5's too new for this beast. Anyone out there have a keyboard/mouse they're willing to part with (or know where I can find one?). This thing's got a 15-pin D-Sub connector on it and I of course don't have anything compatible... Thanks, as always... - Josh

Looking for Acorn A5000 keyboard & mouse...

by derschjo＠msu.edu

Man, I seem to be asking for a lot of keyboards lately :). Got a working Acorn A5000 sans keyboard and mouse. Connector looks like PS/2, but of course it's not. Anyone have a spare set? Thanks again, Josh

these RTL or what?

"the mainframe world" acceptance of a CPU is the stupidest-ass thing a company could ever ever want. On a.f.c there were some references to emulating Unisys architectures on Intel hardware, and I followed the links to the trade press rags, and the rags were filled with a bunch of useless self-important balloon-filling about CPU technologies with no evidence that anywhere anyone understood what the emulation layer actually did. I came away not knowing what the emulation layer actually did either (classic CPU-technology-on-the-mind poisoning of those who should know better). There are about ten thousand markets that DEC served quite well, and it's a shame they put all that effort and money into neglecting those markets and trying to do a mainframe. > Even though the 9000s were bombs, they are one of the few VAX machines > I would chase after.

Mainframes are really good at some things, sometimes they are decent number crunchers in terms of pure FLOPS but it has been three to four decades since they delivered any punch in terms of FLOPS per dollar.
